The RTL8187L supports fast receiver Automatic Gain Control (AGC) and antenna diversity functions, and an adaptive transmit power control function to obtain better performance in the analog portions of the transceiver. It also has on-chip digital-to-analog converters and analog-to-digital converters for analog I and Q inputs and outputs, transmit TSSI and receiver RSSI inputs, and transmit and receiver AGC outputs.

The RTL8187L is highly integrated and requires no 'glue' logic or external memory. It keeps network maintenance costs low and eliminates usage barriers.
